Rear camera vs rear sensor comparison recommendation

pu1. Which one is better? Of course, the rear camera is good, and there are parts where the rear sensor can't detect it well, such as a low barrier, but if there is a rear camera, please hold it

OK

pu2. Can't we just have a rear sensor? I don't know if there's a need for a rear camera

OK

pu3. It's okay with just a rear sensor, but if you have a rear camera, you can park very close
